Specification of Letters Patent.

Patented Sept. 13, 1910.

Application filed March 10, 1910. Serial No. 548,418.

To all whom t may concern:

Be it known that 1, Former Fnnxon, a citizen of the United States, residing at I-lillsboro, in the county of Montgomery and State of Illinois, have invented certain new and useful Improvements in Cartridge-Fillers, of which the following is a specification.

This invention relates to a safety device for use in mines in connection with the filling of blast cartridges from powder cans.

The principal object of the invention is the construction of what may be termed a, cartridge filler in a. manner such that it may be attached to commercial powder cans of various makes and to so construct the device that when applied to a can it may serve also to cover the outlet from the can and thereby safeguard the contents thereof.

To this end the invention consists in the structure and combination of arts substanand claimed.

In the accom anying drawings which form a part of tliis specification, Figure 1 represents a complete cartridge filler shown in perspective; Fig. 2 represents a vertical, transverse, medial section thereof; Figs. 3 and 1' represent in perspective the upper ends of two powder cans of commerce, showing attachments; and Fig. 5 represents a powder can like that seen in Fig. 4 with the cartridge filler of this invention applied thereto, and Fig. (5 is a sectional, View of the cap employed for closing the pouring opening .in the can.

To make a cartridge filler universally applicable it is necessary that it be capable of attachment to all the closure securing means of the powder cans of conunerce. One form of closure attaching means in common use is indicated in Fig. 3, and consists of a plate 6 secured about the opening 7 of the can, the edges of which plate converge toward one end as indicated. To this plate the closure is secured. Another can in common use has its closure securing means formed substantially as indicated in Fig- 4, wherein a plate, as 8, is secured at the outlet- 7, which plate has lugs 9 formed integral therewith for holding the closure in place. filler in question has therefore a plate, as 10, with downwardly and ;,inwardly bent converging edges adapted to slidelinto engagement with the converging edges of the plate 6 of the can in Fig. 3. In this platelO The cartridge is an opening provided with a screw-threaded nipple 11 which comes into alinement with the opening 7 when the plate 10 is located upon the can in Fig. 3. Fitted to the nipple 11 is a nozzle 12, flanged at its lower edge, as indicated at 13, for close engagement with the plate 10-. Through this nozzle the powder is poured from the can into the cartridge. A cap, as 14, is fitted to the nozzle 12 for closing the opening in the can after pouring the powder therefrom.

In adapting the cartridge filler just described to the can shown in F ig.- 4 the nozzle 12 is removed from the plate 10 and placed over-the opening 7 of said can and the lugs 9 bent up over the flange 13, thereby securing it snugly in place over said opening. Powder may then be poured through the nozzle into the cartridge and after pouring the can may be closed by placing the cap 14: upon the nozzle. v

The cartridge filler as shown in Fig. '1 is therefore adaptable to either form of can illustrated and when sold to a mine using the form of can seen in Fig. 3 the filler in its entirety, as seen in Fig. 1, willbe used, and when sold to a mine using the cans illustrated in Fig. 4 the plate 10 will be discarded and the nozzle 12 with its cap used. Obviously the plate 10 may have other forms 'than that illustrated whereby to render the filler tl1))l1()tll)l0 to cans provided with other forms of closure securing means.

The invention claimed is 1. An article of manufacture cousistiugof a cartridge filler constructed for application tovarious powder cans of conuncrce and comprising a plate formed and adapted for attachment to theordinary closure-setmriug means on certain makes of powder cans and provided with a screw nipp e, a flanged nozzle, screw-threaded for attachment to said nipple,'said flange being of a form and size adapting it for attachment to the ordinary closure securing means on other makes of powder cans, and means for closing the nozzle after use, thereby closing the powder can in both instances.

2. An article of manufacture consisting of a cartridge filler constructed for application to various powder cans of commerce and com )rising a plate provided with downwart 1y recurve converging edges, whereby it is adapted to be slidiinto engagement wit 1 a corresponding plate secured to the outlet nozzle whereby to close either make of pow of one form of powder can said slidable der can after use. 11) plate having a nipple projecting therefrom In testimony whereof I 211%; my signature to come into alinement wlth said outlet, a 'in presence of two witnesses.
